In a world where messages are delivered via mysterious voices rather than written notes, players assume the role of a charismatic detective named Vance Echo. Vance is known for his flippant attitude and uncanny ability to decipher the intentions behind these elusive greetings. Each hello introduces a new suspect with a unique alibi, and Vance must unravel the truth while navigating relationships with quirky sidekicks, charming adversaries, and even a mischievous talking cat. As players collect information and make choices, the narrative dynamically shifts, leading to multiple endings based on the social dynamics explored throughout the story.
